This invention relates to the construction of houses or other buildings primarily adapted to use slabs of concrete or the like in the construction of the walls thereof, whether the interior or exterior side walls, the ceiling or the floor.

It is particularly aimed to provide novel means whereby the slabs may be readily connected to the joists, studs, beams or other structural elements and be of such a nature that all of the material or parts necessary may be made in the factory and delivered to the job or place of use, especially to erect small, economical houses with air-spaced and insulated walls, floor, ceiling and roof.

It is also aimed to provide such structure wherein the slabs and associated parts may be used in applying the slabs to houses or buildings already built.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a fragmentary vertical sectional view through a house or building embodying my improvements;

Fi ure 2 is a horizontal sectional view taken on the plane of line 22 of Figure 1;

Figure 3 is a vertical sectional view taken on the plane of line 33 of Figure 1;

Figure 4 is an enlarged vertical sectional view of portions of slabs forming the inner side wall of the building and associated parts;

Figure 5 is a detail perspective view of a side wall slab attaching bracket;

Figure 6 is a detail perspective view of a ceiling suspending clip;

Figure 7 is a view similar to Figure 4 showing a modified form of attaching bracket;

Figure 8 is a vertical section taken on the line 88 of Figure 7;

Figure 9 is a vertical sectional view showing a modified form of ceiling slab attaching means;

Figure 10 is a vertical sectional view showing a modified form of attaching means for the outside wall slabs;

Figure 11 is a vertical sectional view through a modified form of means for attaching ceiling slabs;

Figure 12 is a horizontal section taken on the line l2-l2 of Figure 11;

Figure 13 is a vertical section of a further modified form for attaching ceiling slabs;

Figure 14-. is a vertical section through a modified form of ceiling and side wall joints, and

Figure 15 is a horizontal section taken on the line |5-l5 of Figure 14.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, a house or other building is but fragmentarily shown, embodying parts of inner and outer side walls and ceiling but it is to be understood that the same principles may be practiced in the construction of the floor, roof, and other walls or parts. Specifically, the side of the building frame comprises fabricated metallic I beams as at l0 and for the support of the ceiling, has

concrete or other beams or joists as at l l The outside walls may consist of slabs l2 of concrete or the like which are interlocked as at H with the aid of mortar, .any other sealing medium or the like and the exterior of which slabs after they have been applied may be finished with stucco or any other suitable material. Bolted to the beams ID as at M are attaching brackets l5 for the slabs. Such brackets are shown specifically in Figure 5. They have attaching portions or walls l6, forwardly extending walls l1 and I8 from which rise in spaced relation, lower and upper hook flanges l9 and 20 respectively. Said slabs l2 have hooks 2| engageable over the hooks. I9 and 20, and such hooks 2| have attaching portions 22 embedded in the material of the slabs.

It will be realized that in the construction described, the slabs l2 may be readily attached by engaging the hooks 2| with the flanges l9 and 20, following which the joints at l3 are pointed up, having previously had an application of concrete, mortar or other sealing medium applied thereto, and following which, the exterior may be finished with stucco or any other desired way. If desired, spacing battens 23 may be interposed between the slabs l2 and the beams Ill, preferably fastened to the latter.

The interior wall may consist of a series of slabs 24 preferably of the same material as those at l2 and which are joined along concave-convex surfaces at 25, with mortar or a sealing medium interposed. Such slabs have hooks 26 with ends embedded therein and which hooks 26 are detachably engaged with adjacent flanges l9 and 20 of the brackets l5 adjacent to the same, and fastened like the other brackets, by bolts M to the beams II]. It will be realized that these slabs 24 may be readily applied to the adjacent brackets l5 and the joints as at 25 effectively closed or sealed.

At the ceiling, the Wall preferably consists of a series of slabs 21 of the same material and shape and with the same joints as the slabs 24. Marginal slabs or rows may be supported from an adjacent concrete beam or joist ll through the engagement of hooks 28 thereon with projections 29 anchored in the beam.

Brackets, loops or clips 3|, as detailed in Figure 6, have terminals 32 anchored or embedded in certain of thejoists II and they are overlapped by free terminals of hooks 30, preferably from opposite sides, anchored in the slabs 21, the slabs 2'! thus being suspended from the joist H.

In lieu of the concrete or cementit ious joists ll, metallic joists or I beams may be employed as at 33, in Figure 14 and by means of rivets 34, plates 35 are secured to such joists or beams. The

adjacent slab 21 has a fastening 38 embedded therein provided with a head at 38' which is adapted to pass through a T-shaped slot 36 of the plate 35 and then rest thereon to support the adjacent portion of the ceiling.

As shown in Figure 9, where a joist I I of metal is used in place of that at H, a modified form of the loop or bracket 3! is provided at 39 in the form of U-bolt having its legs passing through flanges of the joist H and secured thereto by nuts 41 threaded on the legs 40.

The bracket l5, rather than being permanently fastened or bolted in place may be detachably applied asby means of an enlarged slot 42, having an enlarged entrance opening 43 by means of which the bracket, here designated I5, may be engaged over a head of a bolt 44 on the beam H3, and supported by such bolt. This form of bracket 15 may be used for either slabs l2 or 24 as preferred.

In Figure 10, a modified form of bracket is used for the support of the slabs 12, the same being designated 45 and bolted as at 46 to a stud or beam ID. This bracket 45 has parallel portions 41 offsetting oppositely extending flanges 48 which are detachably engageable by the hooks 2|.

In lieu of the suspension of the ceiling slabs 21 from the elements 3|, they may be suspended from brackets 49, of the same shape as used at 45, the same having attaching portions 50 and L-shaped slots 5| engaged by bolts or screws 52 fastened to cement joists Ila. The heads 52 of such bolts are passed through slots 5| and the brackets thereafter rest on such heads. Said brackets have U-shaped portions at 53 from which hook flanges 54 extend in opposite directions and are engageable by hook members 55 embedded at 56 in slabs 2"! identical with those at 21.

Figure 13 illustrates the ceiling slab supported from a metal beam or joist Hb in lieu of the joist Ha. In this form, the bolt 53 corresponding to that at 53 is connected to one of the flanges of the beam Hb. Otherwise the structure is identical with that of Figures 11 and 12.

Particular attention is called to the fact that the hooks of the different forms are employed at adjacent edges of adjacent slabs and engage the same or a common bracket, thereby insuring that the joints between the edges of the slabs will be smooth and flush.

. Various changes may be resorted to provided they fall within the spirit and scope of the invention.
